The short answer

HVAC Problems We Repair

Most calls start with a system that won't turn on, runs without heating or cooling, or makes a new noise. We work on:

  • Furnaces that short-cycle, blow cold air or fail to ignite
  • Central air conditioners that run but don't cool, or freeze up
  • Heat pumps stuck in one mode or struggling to keep up
  • Thermostat, wiring and control board faults
  • Blower motor, capacitor and fan problems
  • Refrigerant leaks and condensate drainage issues

How the Valley's Climate Affects Your System

The Santa Clara Valley has a Mediterranean climate, with dry summers and mild, damp winters. Inland and southern parts of the valley run noticeably hotter in summer than neighborhoods closer to the Bay. As a result, air conditioners in the southern part of the county may work harder than those near the Bay.

Because winters are mild, many furnaces sit idle for months and then run hard on the first cold nights. Problems like dust buildup, worn igniters and weak capacitors often show up then. A check before the season changes can catch these problems early.

Repair or Replace? What Local Rules Mean

Bay Area Air District rules do not require you to replace working equipment. They apply only when an existing furnace or water heater fails or is replaced. If your system can be repaired, repairing it is often the simplest path.

Planning ahead still helps. Under the Air District's furnace rule, natural gas furnaces manufactured from 2029 must meet a zero-NOx standard. In practice, that points homeowners toward heat pumps for replacements after that date. For small water heaters, the zero-NOx date was set for 2027. The Air District Board is considering amendments in November 2026 that could delay it, so check the current rule before planning a replacement.

The federal 25C tax credit covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations. You can check BayREN and your local clean energy provider for current incentives. Amounts change by funding cycle, so we confirm the current offer before quoting it.

What to Expect From a Repair Visit

A technician inspects the system, tests the parts tied to your symptoms, and tells you what failed and why. You get a clear explanation of your repair options before any work starts. If replacement makes more sense, we explain the reasons and the trade-offs without pressure.
